-- sounds like you will soon have it under control. Have you tried just reinstalling the needle? -- perhaps it was just set too low by the previous user.
@itchy might try that. I got a set of instructions from the gallery what is the best way to clean the crud in there? And is it better to preheat with meth instead of petrol i find petrol dirty and when I clean it up I'd like it to stay that way
Priming with meths is the cleaner option, by far. Few, if any, drawbacks other than the need to carry two fuels. But, do you have access to a cleaner fuel than petrol? Coleman fuel is probably ridiculously expensive but 4-cycle "clean" fuel for small engines (at garden centers, etc) and other options might be available. You want something that is mostly heptane (n-heptane).
Have a read of this before attempting to re-fit the cleaning needle: https://classiccampstoves.com/threads/fitting-replacement-parts-on-regulated-burners.8843/ Best Regards, Kerophile.
Clean the “crud” inside the workings with carburettor cleaner; leave the graphite packing in place and refit it with a drop of light oil. Run the stove on naphtha not car petrol. Prime with metho (meths). Tony
@itchy @kerophile Sorted out the needle think the previous owner set it wrong working fine now I'm thinking of lightly cleaning the rust and paint and maybe clear laqure it.
Wire brush and clear coat it to halt the rust. Easily removed if you want to restore in the future. Alec.
@itchy @kerophile the previous owner bought this in the mid 70s and it can with both multi tool key and control knob. After looking through the gallery it looks like it the later model with no spanner clip But I've noticed the flame plate has groves in it. is it old stock on the newer model?
I think it's original. The previous owner got tired of getting burnt fingers using the multi tool key so added a control knob.
